As one of the common auxiliary parts in construction machinery, large excavator breaker hammer has been widely used in mining, highway, municipal and other work occasions. As we all know, the hydraulic breaker hammer of large excavator in daily work is a "hard bone" working environment poor conditions, master the correct method of using the breaker hammer, not only can improve work efficiency, but also greatly extend the service life, reduce the frequency of failure.
We often need the help of a crushing hammer on the construction site, but when using the breaker hammer, some people think that it is very durable, and some people think that it is easy to damage, why is there such a big gap? So how should we extend the life of large excavator breaker hammer?
1. the physical properties of the mineral and the properties of the associated organisms (abrasive properties of the metal, soil content, moisture, viscoplasticity, compressive strength, etc.); This is an objective existence, is congenital, we need to have a correct understanding in advance.
2. the rationality of the internal structure of the large excavator breaker hammer.
3.the correctness and manufacturing quality of the selection of large excavator breaker hammer head.
4. Operation method of large excavator breaker hammer.:When running the crushing work, please make sure that the direction of the drill rod point is perpendicular to the surface of the crushing object, and keep it as much as possible at any time; If it is inclined to the surface of the broken object, the drill rod may slide away from the surface, in which case it will cause damage to the drill rod and affect the piston. When breaking, please first select the appropriate strike point. And confirm that the drill rod is really stable, and then strike.The use of large excavator breaker hammer in this way is not only doubles the efficiency, but also extends the service life of the machine!
1.Step forward, Fractional crushing broken
Move the impact point gradually from the edge to the inside, do not try to break the larger body at once, if it cannot be broken within 30 seconds, it should be broken in stages. When breaking particularly hard objects, should start at the edge, do not continuously beat at the same point for more than a minute to prevent the drill rod burn or hydraulic oil overheating.
2. The striking Angle is less than 90 degrees
When crushing, the crusher should have an internal Angle of less than 90 degrees for the broken material, and the excavator should constantly adjust the internal Angle for crushing during vibration. There will be some deviation between the direction of the bucket teeth entering the broken object and the direction of the breaker hammer itself, please always pay attention to adjusting the bend arm of the bucket in use to maintain the same direction of the two.
3. Select the appropriate strike point:
Before the attack, first impact a point, the high level of 60 to 70cm, and then lift the hammer, the displacement to the original impact point of 30 to 40cm or so the distance to crack again, so that there will be better results.
4. install the water check valve before launching:
If underwater work is required, a check valve must be installed on the top cover of the vibration box.
5.to prevent empty:
When the broken object has been broken, please immediately release the breaker hammer operating pedal to stop the breaker hammer. Otherwise (the drill rod is not fixed in the case of hitting) between the piston and the drill rod, between the drill rod and the drill rod pin, between the drill rod and the drill rod pin, and between the drill rod pin and the front jacket, so that the drill rod, the drill rod pin, the front jacket is damaged.
The use of large excavator breaker hammer in this way is not only doubles the efficiency, but also extends the service life of the machine! Large excavator breaker hammer is a key part of crushing equipment, but also easy to wear parts, in addition to the operation skills worth noting, but also pay attention to daily maintenance. Because the working conditions of the breaker hammer are very bad, the correct maintenance can reduce the failure of the machine and extend the service life of the machine, so as to greatly improve the work efficiency and reduce the use cost.
